ummm oh yes, just put it through the hole, i'll take special care of it....you like it hard? rough? slow? fast? deep? just as long as i get to swallow the load
My favorite bathhouse has the same types of big glory holes with open areas at the bottom of the walls. I wait until a guy in good looking thong sandals goes in the next room. I lure him over and start giving an incredible blowjob. when he is about to cum I reach down and grab his toes in the sandals. His explosion in my mouth is twice as bug.
